Providential timing with Thursday’s 7.0, 4.7 mag and multiple more quakes along Nor Cal coast

WASHINGTON, D.C. — Today, U.S. Senators Alex Padilla (D-Calif.) and Lisa Murkowski (R-Alaska) announced that the Senate passed their bipartisan legislation to reauthorize the National Earthquake Hazards Reduction Program (NEHRP) through Fiscal Year 2028. Senate passage of the bill comes after a series of major earthquakes struck Northern California this morning, triggering tsunami warnings and underscoring the urgent need for early warning systems and earthquake safety programs like NEHRP. The legislation now heads to the U.S. House of Representatives.

The bill would authorize a total of $175.4 million per year from FY 2024-2028 across the four federal agencies responsible for long-term earthquake risk reduction under NEHRP: the Federal Emergency Management Agency (FEMA), the National Institute of Standards and Technology (NIST), the National Science Foundation (NSF), and the United States Geological Survey (USGS).

“As today’s devastating Northern California earthquakes remind us, it is never a matter of if, but when the next major earthquake will strike,” said Padilla. “The National Earthquake Hazards Reduction Program supports crucial tools like the ShakeAlert Earthquake Early Warning System, advances scientific understanding of earthquakes, and strengthens earthquake resilience in communities nationwide. With the safety of our communities at stake, we must stay vigilant. After today’s unanimous Senate passage, I will push my House colleagues to pass this bill to reauthorize this critical program as soon as possible.”

He was referring to both a 7.0-magnitude earthquake, 45 miles off the coast of Eureka and another 4.7 magnitude quake near Ferndale as well as multiple others throughout the day. (See Latest Earthquakes on the U.S. Geological Survey website)

“Alaska faces significant earthquake risks as the most seismically active state-our communities must be prepared,” said Murkowski. “The National Earthquake Hazards Reduction Program Reauthorization Act provides crucial funding to federal agencies for the research, development, and implementation of earthquake safety procedures. The earthquake today in Northern California is a sober reminder of how critical these readiness measures are.”

Specifically, the NEHRP Reauthorization Act of 2024 would authorize $10.6 million for FEMA, $5.9 million for NIST, $58 million for NSF, and $100.9 million for USGS per year from FY 2024-2028. This funding would support research, development, and implementation activities related to earthquake safety and risk reduction.

This NEHRP reauthorization includes:

• Directing state and local entities to inventory high risk buildings and structures,
• Expanding seismic events to include earthquake-caused tsunamis;
• Providing more technical assistance to Tribal governments; and
• Improving mitigation for earthquake-connected hazards.

California faces substantial earthquake risks. According to the California Department of Conservation, over 70 percent of Californians live within 30 miles of a fault that could cause high ground shaking within the next 50 years. The state averages two to three earthquakes per year at magnitude 5.5 or higher, risking moderate structural damage. Because of these major earthquake risks, California has become a leader in earthquake research.

The NEHRP Reauthorization Act of 2024 is endorsed by the American Society of Civil Engineers (ASCE), BuildStrong America, Earthquake Engineering Research Institute (EERI), International Code Council (ICC), the National Council of Structural Engineers Associations (NCSEA), the National Institute of Building Sciences (NIBS), Seismological Society of America, and the Structural Engineers Association of California (SEAOC).

Senator Padilla has long been a leader in mitigating earthquake risks. As a California State Senator, Padilla authored Senate Bill 135, signed by Governor Jerry Brown in 2013, which required the state to establish the nation’s first statewide early warning system. In 2021, he led five of his U.S. Senate colleagues in requesting details from the U.S. Geological Survey (USGS) on future plans and funding needs for the West Coast Early Earthquake Warning system.

One large quake last Wednesday, two more smaller quakes on Monday

By CA Department of Water Resources

News of yet another earthquake in the heart of the Delta in the last week is a serious reminder about the importance of modernizing and protecting water supply infrastructure. The quake on Wednesday, Oct. 18th measured 4.2 and was centered 5 kilometers southwest of Isleton.

Two more quakes measuring 2.9 magnitude and 2.5 mag, with epicenters 4 km southeast of Rio Vista, occurred on Monday, Oct. 23, according to the US Geological Survey (USGS).

In a report by CBS News last week, Austin Elliott with the USGS said that “a very large earthquake, centered near the Delta, would pose a particularly significant threat to both protective systems that the levees provide, as well as the water distribution and intake systems.”

He also said that “Larger earthquakes magnitude — five or six — would begin to produce liquefaction and damage some of the infrastructure and geotechnical work there.” And according to the USGS, there is a 72 percent chance of a 6.7 or greater magnitude earthquake occurring in the Bay Area by 2043.

The Delta Conveyance Project is meant to help the State Water Project guard against these seismic threats.

DWR has also invested millions of dollars to reinforce many Delta levees through the Delta Levees Special Flood Control Projects programs. Additionally, DWR has been planning for and strategizing how to address the earthquake risk and potential disruption to California’s water supply and has developed detailed plans to guide response and recovery efforts.

For more information on how the proposed Delta Conveyance Project would make California’s water supply more earthquake resilient, check out this digital article and these two in-depth videos (Part 1 and Part 2).
